One removes the file from your computer, and the other tries to heal the infected data. Quarantine moves the offending file. Knowing which action to take in a given situation is crucial to the health of your computer. Here's a quick rundown of their functions:. Deletion is tricky. If you instruct your antivirus software to delete all infected files, some that are crucial to your computer's operating system might get deleted.
This could affect the functionality of your operating system and programs. Cleaning can be useful, but antivirus software can't clean a worm or a Trojan because there is nothing to clean; the entire file is the worm or Trojan.
Quarantine occupies the middle ground, moving the file to safe storage that's under the control of the antivirus application so that it can't harm your system. This gives you the option to restore the file in case you decide the file was mistakenly tagged as harmful.
Generally speaking, the best option for a worm or Trojan is to quarantine or delete. If it's a true virus, the best option is to clean. However, this assumes you are able to distinguish exactly what type it is, which might not always be the case. The best rule of thumb is to proceed along the continuum from the safe option to the safest. Then it makes changes to the file so that it cannot run as a program, and puts it in a hidden folder that other programs cannot see or access.
It's in a hidden, high-security jail. You can simply ignore quarantined files. For most people, this is uncomfortable.
However, if you're not sure how to proceed, it's a safe option while you find out more. Most modern viruses make their own files, which contain nothing but the virus waiting for an opportunity to infect your computer. If all your programs are running fine, and your system isn't crashing, you can happily delete those files.
You may find files in quarantine that surprise you: files that have been on your computer a long time, or files that a program needs in order to run. These may be the victims of a false alarm. If a program won't run because a file is in quarantine, use your discretion before restoring it or adding it to exceptions. Read up about the suspected virus and see if it makes sense.
